ok I don't know why it doesn't work in your case, but I can help you to identify the problem and maybe you can find a solution for yourself. 1) error in Lidar.cpp(102), I think there are some problems when passing this function. You can quick fix it by replacing FConversions::MToCm to 100 * , for example float RangeMinInCm = 100 * RangeMin; 2) error in StateManager.cpp(88) and below. For some reasons the GetActorLabel doesn't work, it might be because you didn't build it in the Editor mode, but in Game mode. Anyway, I think the StateManager is deprecated since I wanted to change the interface from ROS to ZMQ and somehow I forgot to change it back. You can remove StateManager.cpp in Private, StateManager.h in Include and its variable in RoboManager.h and RoboManager.cpp.

Hope it helps
